You may have stumbled upon this instructable and thought, "How does that work? Fire and water? Is that possible?" In short, yes (due to a little bit of chemical illusion). This instructable will show you how. But first, you may want to watch this video:

Step 1: First, You Need to Get the STUFF!

Firstly, you need to get the materials that you need to do the expirement. Starting with Potassium or Sodium. You can buy both of these, but you can also make Potassium. You can learn how to do that here. Secondly, you will need diethyl (ethyl) ether. You will need to buy that but it is worth it. You also need water which is easily attainable, and Sodium if you want to compare results.

Potassium
Diethyl Ether
Water
Beaker
Sodium (optional)

Step 2: Setting Up and Cautionary Warnings

Firstly, this experiment deals with fire, as well as a potassium and water reaction. So we need to inform you of the possibility of danger and risk of harm. Now that this information is out of the way, let's start setting up shall we? Firstly, you will need (depending on the size of reaction you want) 1-3 "chunks" of potassium. Put that in a beaker, and then cover the bottom of the beaker (only the bottom, too much can cause problems) with diethyl ether.

Step 3: Fire!

Once you have the potassium and diethyl ether in the beaker, now is time for the fun part. Please be sure to have safety goggles when performing this step. Simply put the water in the potassium/sodium and stand back. These will mix and create a reaction (a spark) which ignites the diethyl ether, creating fire.

Step 4: In Conclusion...

So, if you followed these steps correctly, you should've made "fire water". This is a beautiful reaction and is great to watch. Here is what our reaction looked like:
